Types of Jigsaw Blades

There are 4 main types of jigsaw blades based on material:

  • High Carbon Steel (HCS) Blades: In my experience, HCS blades are perfect for softer materials like wood and plastic. They’re flexible, which helps prevent breakage, but they can wear out quickly on harder materials. I’d recommend HCS blades for general-purpose woodworking tasks where durability isn’t a top concern.
  • High-Speed Steel (HSS) Blades: When I need a blade that lasts longer and can handle tougher materials like metal, I go for HSS blades. They’re harder than HCS blades but can be more brittle. HSS blades are ideal for cutting non-ferrous metals, hardwoods, and even some plastics.
  • Bi-Metal (BIM) Blades: BIM blades combine the best of both HCS and HSS blades. They have an HSS cutting edge for durability and an HCS body for flexibility. I personally love BIM blades for their versatility – they’re great for a variety of materials and tend to have a longer lifespan.
  • Tungsten Carbide (TC) Blades: When it comes to cutting ceramic, tile, or other abrasive materials, I always choose TC blades. These blades are incredibly hard and wear-resistant, making them perfect for tackling challenging materials.

T-Shank vs. U-Shank Blade

When it comes to jigsaw blades, there are two primary shank types: T-shank and U-shank. Understanding the differences between these two types is essential, as it directly affects your jigsaw’s performance and compatibility with various blades.

The majority of jigsaws nowadays use T-shank blades for their improved stability and quick-change capabilities. However, some older models still require U-shank blades. Always double-check your jigsaw’s compatibility before buying new blades.

T-Shank Blades

T-shank blades are the most popular option among modern jigsaws due to their improved stability and quick-change capabilities. The “T” shape allows for a more secure fit in the jigsaw’s clamp, minimizing wobble and providing better control when cutting. Most jigsaws today, including my personal favorites, have a tool-less blade change system that makes switching out T-shank blades a breeze. As a result, they save time and effort when working on projects that require frequent blade changes.

U-Shank Blades

U-shank blades, on the other hand, have a “U” shaped cutout at the top and are typically used with older jigsaw models. Although U-shank blades can still provide satisfactory cutting performance, they lack the stability and quick-change benefits that T-shank blades offer. It’s important to note that some jigsaws may still require a tool to change U-shank blades, making the process more time-consuming and cumbersome.

Are T-shank and U-shank jigsaw blades interchangeable?

No, T-shank and U-shank jigsaw blades are not interchangeable due to differences in their design and the way they are secured in the jigsaw. T-shank blades have become the industry standard for most modern jigsaws due to their improved stability, quick-change capabilities, and better overall performance. T-shank blades feature a “T” shape at the top of the blade, which allows them to slide into the jigsaw’s blade clamp and lock in place without the need for additional tools.

On the other hand, U-shank blades, also known as “universal” shank blades, have a “U” shape at the top of the blade. These blades require a screw or some other locking mechanism to secure them in place within the jigsaw. U-shank blades are typically compatible with older jigsaw models that were designed before the widespread adoption of T-shank blades.

Since the designs and attachment methods of T-shank and U-shank blades are different, they are not interchangeable. Always consult your jigsaw’s user manual or the manufacturer’s website to determine the appropriate shank type for your specific jigsaw model, and ensure that you purchase compatible blades.

Feature T-Shank Jigsaw Blades U-Shank Jigsaw Blades
Design “T” shape at the top of the blade “U” shape at the top of the blade
Compatibility Commonly used with modern jigsaw models Compatible with older jigsaw models
Stability Improved stability during cutting Less stable compared to T-shank blades
Attachment Method Tool-less, quick-change blade clamp system Requires a screw or locking mechanism
Industry Standard Widely adopted as the industry standard Less common, mainly used in older jigsaws
Availability of Blades Wide range of blades available on the market Limited selection compared to T-shank blades


Before purchasing new blades for your jigsaw, always double-check the compatibility of your specific jigsaw model. Most jigsaw manufacturers will indicate the shank type in the product manual or on their website. If you’re unsure, consult jigsaw’s user manual or contact the manufacturer’s customer support for guidance.

In my experience, if you’re using a newer jigsaw, it’s best to opt for T-shank blades for their enhanced stability, ease of use, and broad compatibility. However, if you have an older jigsaw that requires U-shank blades, don’t worry – they can still get the job done. Just remember to factor in additional time for blade changes and ensure you have the necessary tools on hand.

Blade Tooth Configuration

Understanding blade tooth configuration is essential for achieving the best possible results with your jigsaw. Tooth spacing, pitch, and direction all play a significant role in determining the speed, cut quality, and overall performance of your blade.

Tooth Spacing and Pitch

Tooth spacing and pitch refer to the distance between individual teeth on a jigsaw blade and the angle at which they’re set. These factors affect how the blade interacts with the material being cut and, ultimately, the final outcome of your work.

  • Fine-toothed blades: These blades have closely spaced teeth and are perfect for cutting thin materials, such as sheet metal or thin plywood. They produce clean, smooth cuts with minimal tear-out. However, their cutting speed is generally slower due to the finer tooth configuration. I often use fine-toothed blades when I need precision and a high-quality finish on my projects.
  • Coarse-toothed blades: Coarse-toothed blades have widely spaced teeth, making them ideal for cutting thicker materials, such as construction lumber or solid wood. These blades excel at producing faster cuts, but they tend to leave rougher edges. I usually turn to coarse-toothed blades when I need to make quick cuts and don’t require an ultra-smooth finish.
  • Variable-toothed blades: Variable-toothed blades feature a mix of tooth sizes and spacing, offering a nice balance between cutting speed and smoothness. They’re versatile and suitable for cutting various materials, from plywood to plastic. I’ve found that variable-toothed blades are a great option when working on projects with diverse cutting requirements.

Tooth Spacing and Pitch Measurement

Tooth spacing and pitch are measurements that help describe the arrangement of teeth on a jigsaw blade. They play a crucial role in determining the cutting speed, smoothness, and overall performance of the blade. Here’s a closer look at how these measurements are defined and calculated:

Tooth Spacing

Tooth spacing, also known as tooth set, refers to the distance between the teeth of a blade. It is typically measured from the tip of one tooth to the tip of the next adjacent tooth. Tooth spacing is often expressed in TPI (teeth per inch), which indicates the number of teeth within a one-inch length of the blade.

For example, a blade with 10 TPI has ten teeth evenly spaced within one inch of the blade’s length. A higher TPI count corresponds to a finer, more closely spaced tooth configuration, while a lower TPI count signifies a coarser, more widely spaced tooth configuration.

Tooth Pitch

Tooth pitch is another way to describe the distance between the teeth on a jigsaw blade. While tooth spacing measures the distance from the tip of one tooth to the tip of the adjacent tooth, tooth pitch measures the distance from the center of one tooth to the center of the next adjacent tooth.

Tooth pitch is usually expressed in millimeters (mm) and can be calculated by dividing 25.4 mm (1 inch) by the TPI count. For example, if a blade has 10 TPI, its tooth pitch would be 25.4 mm ÷ 10 = 2.54 mm.

In general, a smaller tooth pitch corresponds to a finer tooth configuration, resulting in smoother cuts. A larger tooth pitch corresponds to a coarser tooth configuration, yielding faster cuts but potentially rougher edges.

When choosing a jigsaw blade, consider both the tooth spacing (TPI) and tooth pitch to select a blade that best suits your cutting needs and desired finish.

Tooth Direction

The direction in which a jigsaw blade’s teeth are oriented affects its cutting performance and the final result.

  • Regular teeth (ground and milled): These teeth are the most common configuration and work well for cutting a wide range of materials. Ground teeth are sharper and more precise, while milled teeth are more durable but slightly less accurate. I use regular teeth blades for most of my projects due to their versatility and reliable performance.
  • Reverse teeth blades: Reverse teeth blades have teeth that point in the opposite direction, cutting on the downstroke. This configuration reduces chip-out and tear-out when cutting laminates, veneers, and other delicate materials. I’ve found reverse teeth blades to be excellent for achieving clean edges on surfaces prone to chipping.
  • Plunge-cutting teeth: Plunge-cutting teeth are designed to allow you to start cuts in the middle of a material without the need for a pilot hole. This feature is useful for making interior cutouts, such as in a countertop or wall panel. I’ve successfully used plunge-cutting blades for tasks where I needed to make intricate cuts without damaging the surrounding material.

Matching Blade to Material

Selecting the right jigsaw blade for the material you’re working with is crucial for achieving optimal cutting performance and a high-quality finish. Here are my recommendations for matching blade types and tooth configurations to various materials:


When cutting wood, I’d recommend High Carbon Steel (HCS) or Bi-Metal (BIM) blades with a coarse-tooth or variable-tooth configuration. Coarse-tooth blades are ideal for making quick, rough cuts in thicker wood, while variable-tooth blades offer a balance between speed and smoothness, making them suitable for cutting plywood, particleboard, and other engineered wood products.


For cutting metals, such as aluminum, steel, or copper, High-Speed Steel (HSS) or Bi-Metal (BIM) blades with a fine-tooth configuration work best. Fine-tooth blades produce clean, precise cuts on metal surfaces while minimizing the risk of binding or creating rough edges. When cutting thin metal sheets, a blade with an even finer tooth configuration may be necessary to prevent unwanted vibrations and ensure a smooth cut.


For cutting plastics, High Carbon Steel (HCS) or High-Speed Steel (HSS) blades with a variable-tooth or fine-tooth configuration provide clean, smooth cuts. Variable-tooth blades are versatile and suitable for cutting various plastic materials, from PVC pipes to acrylic sheets. Fine-tooth blades are perfect for achieving precise cuts on thin plastic sheets or delicate plastic materials.

Ceramic and Tile

When working with ceramic and tile materials, Tungsten Carbide (TC) blades are the go-to choice. These blades are specifically designed to withstand the hardness and abrasiveness of ceramics and tiles, ensuring clean, chip-free cuts. For straight cuts, use a TC blade with a continuous rim, while for intricate cuts or tight curves, a TC blade with a segmented rim or a diamond-grit edge may be more suitable.

Always remember that matching the blade type and tooth configuration to the material you’re cutting is key to achieving the best possible results and prolonging the life of your jigsaw blades.

Tips for Selecting the Right Jigsaw Blade

Choosing the appropriate jigsaw blade is essential to ensure the success of your projects and the longevity of your tools. Here are some tips to help you select the right blade for your needs:

Assessing the material and project requirements

Before selecting a blade, consider the type of material you’ll be cutting and the desired cut quality. Different materials, such as wood, metal, plastic, or ceramic, require specific blade types and tooth configurations to achieve the best results. Think about the thickness of the material and whether you need smooth, precise cuts or quick, rough cuts. Having a clear understanding of your project requirements will help you make an informed decision.

Considering blade life and durability

It’s important to think about how often you’ll be using the blade and whether it’s worth investing in a more expensive, longer-lasting option. For instance, if you work with abrasive materials like ceramic or metal frequently, it may be worthwhile to invest in high-quality, durable blades like Bi-Metal (BIM) or Tungsten Carbide (TC) options. These blades tend to last longer and maintain their cutting performance over time, even under heavy use.

Ensuring proper compatibility with the jigsaw

Before purchasing a new blade, make sure it is compatible with your jigsaw model. Most modern jigsaws use T-shank blades, which offer improved stability and quick-change capabilities. However, some older jigsaw models still require U-shank blades. Check your jigsaw’s user manual or consult the manufacturer’s website to confirm the appropriate shank type for your tool.

By considering these factors, you’ll be well-equipped to choose the right jigsaw blade for your specific needs and ensure optimal cutting performance throughout your projects. Don’t be afraid to experiment with different blade types and tooth configurations to find the perfect match for your cutting requirements.
